Can EXSLT date-and-time functions be used in XSLT 1.0 and processed using browser engine?

My goal: I need to transform a "date of birth" element in XML document to "age" value using XSL stylesheet and generate XHTML page. I am using the web browser (e.g. IE/FF) directly to open the XML document.

I know XSLT 2.0 has built-in dat开发者_C百科e and time functions, but I think no browser currently support this. So, I've been trying to use EXSLT functions instead without success.

Here are my sample test files:

test.xml

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<test>
</test>

test.xsl

<xsl:stylesheet version="1.0"
                 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                 xmlns:date="http://exslt.org/dates-and-times">
<xsl:output method="text"/>
<xsl:template match="/">
     <xsl:value-of select="date:date-time()"/>
</xsl:template>
</xsl:stylesheet>

Error on IE8:

Namespace 'http://exslt.org/dates-and-times' does not contain any functions. 

Error on FF4:

Error during XSLT transformation: An unknown XPath extension function was called.

Does that mean EXSLT is not supported by major web browsers? Do I have to use XSLT proccessor like SAXON/Xalan? Am I doing something wrong? Is there an alternative way?

Use the EXSLT support matrix as a reference:

The following XSLT processors support date:date-time:

SAXON from Michael Kay (version 6.4.2)
Xalan-J from Apache (version 2.4.D1)
4XSLT, from 4Suite. (version 0.12.0a3)
libxslt from Daniel Veillard et al. (version 1.0.19)

libxslt is used by Chrome, Opera and Safari, but date-time() does not work since EXSLT is disabled:

I don't think it makes sense to add functions piecemeal; after nearly 5 years is there still anything preventing libexslt being included in the build and exsltRegisterAll() being called from registerXSLTExtensions() in XSLTExtensions.cpp?

IE uses MSXML, which has the following support:

MSXML4 provided two great extension functions, ms:format-date() and ms:format-time() to aim at the latter problem, but they are not supported in .NET or MSXML3.

There is no ms:date-time() function, but there is an MSXSL extension.

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
    xmlns:ecma ="about:ecma">
    <msxsl:script implements-prefix="ecma">
     <![CDATA[
      function GetCurrentDateTime()
        {
        var currentTime = new Date();
        var month = currentTime.getMonth() + 1;
        var day = currentTime.getDate();
        var year = currentTime.getFullYear();
        return(month + "/" + day + "/" + year);
        }
     ]]>
    </msxsl:script>

<xsl:template match="/">
    <xsl:value-of select="ecma:GetCurrentDateTime()"/>
</xsl:template>

</xsl:stylesheet>

Firefox uses Transformiix, which has support for EXSLT date-time() since FF6.
